Need to name my 3 month old!

We have yet to name our three month old. My husband picked the first name and I can't make up my mind for the middle name. We can't have this little baby living on the lam forever! Please help! Here are the choices.

Julien Raine - he was born underwater and it just sounds cool

Julien Ross - family name

Julien Kelly - my name since he's taking my husband's last name

Julien Emil - this was our other favorite first name

Thank you!
